This study has attempted to figure out the effects of the surface heat of perm rods on hair. For this, after forming perm waves, hair damage and its causes have been investigated with a different hair bleach method. If hair was bleached immediately without shampooing after a perm using the heat of rods, great perm waves were formed. However, severe damage was found on the hair because of the heated rods. In addition, when hair was shampooed and dried after the perm, hair bleach was more effective. It has been confirmed that hair was damaged because of high temperature of the surface of the rods. In fact, the heated rods had a direct effect on hair damage. According to these results, it has been confirmed that heat-based perms can accelerate hair damage. Therefore, it is necessary to perform a study on the minimization of the heating of permanent tools.

Variations of the twenty one metal components (Mg, Al, V, Cr, Co, Sr, Ba, Na, K Mn, Fe, Cu, Zn, As, Hg, Pb, Ca, P, Mo, Cd, Sb) were analyzed in human hair sample by inductively coupled plasma mass spectrometry (ICP-MS). The effect of bleach and permanent wave manipulation on the elemental composition of hair were investigated. It was found that the composition of hair varied with hair bleach and permanent wave. Hair sample was collected from male in the age of thirties. Hair sample (0.05 g) was added to the Teflon digestion bomb together with 1.5 mL of nitric acid and an appropriate amount of In as an internal standard. The sample was then decomposed in the microwave digestion system. In normal hair, the contents of V, Cr, Mn, Fe, Co, Cu, Zn, As, Mo, Cd, Sb and P were increased in permanent wave hair, and Mg, Al, V, Co, Sr, Ba, Na and K were increased in bleached hair. But Mg, Al, Sr, Ba, Hg, Pb, Na, K, and Ca contents were decreased with permanent wave hair, Mn, Fe, Cu, Zn, As, Hg, Pb and Ca contents were decreased with bleached hair.

This research is compared and analyzed variations of the heavy metal contents in human hairs according to treating permanent wave manipulation before and after and permanent wave agents. This is the survey of women's hairs in 19 years old. On the basis of this we would like to analyze a extend of exposing of heavy metal scientifically. Also, we would to show a basic data for the permitted limits of heavy metal to keep the healthy hair The conclusion is as follows.; Mean contents of heavy metal in hairs is 2.11 ppm (Pb), 0.25 ppm (Cd), 2.62 ppm (Ni), 256 ppm (Zn), 8.45 ppm (Cu). In reducing agents (processing lotions) of perm, 1.50 ppm (Pb), 0.03 ppm (Cd), 0.05 ppm (Ni), 15.45 ppm (Zn), 0.86 ppm (Cu) in a perm (S), 2.30 ppm (Pb), 0.05 ppm (Cd), 0.05 ppm (Ni), 13.05 ppm (Zn), 0.65 ppm (Cu) in a perm (T). In oxidizing agents (neutralizer) of perm, 1.40 ppm (Pb), 0.03 ppm (Cd), 0.09 ppm (Ni), 9.05 ppm (Zn), 0.65 ppm (Cu) in a perm (S), 1.50 ppm (Pb), 0.02 ppm (Cd), 0.16 ppm (Ni), 8.00 ppm (Zn), 0.85 ppm (Cu) in a perm (T). Mean contents of lead(Pb) didn't show significant differences according to treating cysteine perm agents, showed it according to 3 treating thioglycolic acid perm agents (p<0.05). Mean contents of cadmium(Cd) showed significant differences (p<0.001) according to 2 treating both perm agents. Mean contents of nickel (Ni) showed neither. Mean contents of zinc (Zn) showed significant differences according to 2 treating cysteine perm agents (p<0.001) and 1 treating thioglycolic acid perm agents (p<0.01). Mean contents of copper (Cu) didn't show significant differences according to treating cysteine perm agents, showed it according to 1 treating thioglycolic acid perm agents (p<0.001).

The purpose of this study is to diagnose actual condition of preference of hair-styling, hair-styling techniques, management, grasping a consumer's consciousness, etc with women living in a city. The survey was gotten to a feminine customer who visited the ten of beauty-shops in shopping center. And statistical data about the actual condition of hair-styling preference realities, hair-styling method and style management was entered into the SPSS statistics analysis system. In brief, be as follows by the results of study. There showed significant difference that noted in hair-style information and basis alternative a beauty salon, there were able to know people whose age is from 20's to 40's got mainly an influence of public media very much and from 40's to 50's got mainly an influence of people around them. Basis alternative of a beauty salon showed significant difference to follow age categories. It appeared that introducing from people around them have a effect on the 20's and 30's, and 40's got an influence of convenience of traffic, and 50's got mainly the shortest distance. In an attitude toward a hair style, especially toward hair cut, a case to do hair cut was most a lot of in own selections, and its result was independent of age categories. The reason that wants to give a chance was most a lot of thinking without an age. Preference length of hair cut showed a significant difference according to age. In permanent section, own selections appeared most regardless of age. And in the permanent motive, also, to have a change appeared most regardless of age. And people had a preference natural to role up to setting regardless of age in permanent wave. In hair color section, women whose age is 20's, 30's, 40's had a motive for a change, on the other hand, 50's and their senior had a motive for a gray hair. Women of all over the age almost knew a fashion color, and they had a preference brown color. In a preference way along a hair color kind, there was a significant difference according to age, also. 20's and 30's did mainly 'semi-permanent coating' and 40's and 50's did mainly 'permanent hair color'. In a attitude about a hair-style management, the more age is young, the more a period is long term. And the more age is old, the more the outlay for price of cut is expensive. But, on the contrary, permanent price showed that the more age is young, the more the outlay for price of permanent is expensive. In hair color, the more age is old, the more a period is short and the more price is low.
